Strains of different origins belonging to the two species of fungi imperfecti Cylindrocarpon ianothele and Calcarisporium arbuscula exhibit difference in their morphological or physiological appearances. We have attempted to determine if these variabilities could also be observed at the level of other phenotypic markers, the enzymes glucose-6-phosphate dehydrogenase, alcohol dehydrogenase, octanol dehydrogenase and malate dehydrogenase. Isozymes were separated by polyacrylamide gel electrophoresis and demonstrated isozyme variability as a function of growth and physiological states of a given strain. At the same state of development, the different strains exhibited highly heterogeneous isozyme groups which appear difficult to use for taxonomic purposes.

Two large colonies, originating from allopatric populations of Glossina pallidipes Austen, in the Shimba Hills and Nguruman, Kenya, which differ biologically and with respect to vectorial competence, were compared at fourteen enzyme loci using polyacrylamide gel electrophoresis. The colonies had similar levels of genetic diversity with approximately half of the loci being polymorphic, an average of 1.6-1.7 alleles per locus, and a mean heterozygosity per locus of approximately 18.4%. However, the colonies differed significantly in allele frequencies at the loci for phosphoglucomutase, glucose-6-phosphate dehydrogenase, xanthine oxidase, octanol dehydrogenase and phosphoglucose isomerase. The results were compared with earlier studies on this species and no evidence was found for selection of specific alleles during establishment or maintenance of colonies of G. pallidipes, nor were specific chromosomes, or marker genes, associated with the biological differences between the two colonies.
